Round Sling Capacity Chart: How to Calculate Safe Lifting Angles

When it comes to lifting heavy loads, calculating the proper capacity of your round sling is crucial to ensure a safe and successful lift. One often overlooked aspect of this calculation is the angle at which you're lifting. In fact, using slings at an angle can quickly become deadly if not considered prior to selecting which sling to use.

To calculate the capacity reduction due to angle, start by dividing the sling height (H) by the sling length (L) to determine the Reduction Factor (RF). Then, read across the Angle Chart to find the corresponding number in the Reduction Factor column using the angle from horizontal. This will give you a sense of what the rating would be for each sling rigged at that angle.

Next, calculate the Lifting Weight (LW) multiplied by the Tension Factor (TF) to determine the Minimum Sling Rating for a single leg and hitch type. To do this, divide the sling length (L) by measured height (H), and then use the angle from horizontal to read across the Angle Chart to find the corresponding TF column.

It's also important to consider the Load Angle Factor (LAF) or Tension Factor (TF), which dictates that lifts with angles of less than 30 degrees from horizontal are not recommended. In fact, the most desirable angle of lift is one that approaches 90 degrees.

By understanding the effect of angles on sling capacities, you can ensure a safe and successful lift every time. Remember to always consider the angle at which you're lifting when selecting your round sling capacity chart, and never compromise safety for convenience.
